Hyperlink. Corsi on- line informatica. Graph theory. Refer to the glossary of graph theory for basic definitions in graph theory.

Definitions[edit] Definitions in graph theory vary. The following are some of the more basic ways of defining graphs and related mathematical structures. Graph[edit] Other senses of graph stem from different conceptions of the edge set. All of these variants and others are described more fully below.
Category:Graph algorithms. Information architecture. Introduction This lesson discusses ideas associated with the phrase "information architecture" and relates them to aspects of the library- and information-science (LIS) professions.

Origin of the Phrase, "Information Architecture" The phrase "information architecture" appears to have been coined, or at least brought to wide attention, by Richard Saul Wurman, a man trained as an architect but who has become also a skilled graphic designer and the author, editor, and/or publisher of numerous books that employ fine graphics in the presentation of information in a variety of fields.
Torus interconnect.

Diagram of a 3-dimensional torus interconnect.

It is not limited to 8 nodes but can consist of any number of nodes in a similar rectilinear array. A torus interconnect is a network topology for connecting processing nodes in a parallel computer system. It can be visualized as a mesh interconnect with nodes arranged in a rectilinear array of N = 2, 3, or more dimensions, with processors connected to their nearest neighbors, and corresponding processors on opposite edges of the array connected.[1] The lattice has the topology of an N dimensional torus and each node has 2N connections.
